For regular topology surface, intermediate surface local texture mapping are used; for irregular topology surface, subdivision surface local texture mapping are used. So different topology surface using different texture mapping methods can solve the contradiction between texture effect and processing speed when they are dealt with by single method. The three judge conditions of texture distortion in the process of mapping onto the sphere surface are discussed and the exiting algorithms of mapping are analyzed, the new algorithms of mapping onto the sphere surface are presented.

Results showed that there were significantly positive linear correlations between the toxic effects（probits of mortality and inhibition rate） of chlorpromazine on the two aquatic organisms and the concentrations of chlorpromazine, and the toxic intensity became higher as the exposure time increased. The LC50 values of chlorpromazine acting on Carassius auratus in 24, 48 and 96h were 1.11, 0.43 and 0.32mg·L-1, respectively; and its safe concentration for Carassius auratus was 19.5μg·L-1. The LC50 and EC50 （50% of the tested Daphnia magna inhibited） values of chlorpromazine acting on Daphnia magna in 24h were 0.65 and 0.57mg·L-1, and the LC50 and EC50 values in 48h were 0.36 and 0.28mg·L-1, respectively. Thus, chlorpromazine have high toxicity to Carassius auratus and Daphnia magna, and the latter is more sensitive to chlorpromazine.
